[0 all whom it may concern:

Be it known that I, Onnnno Con'rsz WVY- sons, a citizen of the United States, residing at Greensboro, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Mortising-Machines, of which the following is a specification.

My invention relates to improvements in mortising machines.

One of its objects is to provide a mechanism adapted to mortise chair posts and other articles of similar nature.

Another object is to provide a mechanism in which mortises of varying length, varying distances apart, and in different planes may be simultaneously produced.

Another object is to provide improved and adjustable work holding mechanism, whereby the work can be quickly and conveniently brought to the desired position and clamped, and adapted to hold a variety of different styles of work.

Another object is to provide improved r means for supporting and reciprocating the mortising tools whereby mortises may be made at short distances apart, and a pluality of tools conveniently operated without conflict.

Another object is to provide improved tool spindles and means for adjusting and alininn: the same.

Another object is to provide improved means whereby two operators may independently operate at opposite sides of the same machine, or both sides operated simultzuieously by one operator.

It further consists in certain details of form, combination and arrangement, all of which will be more fully set forth in the description of the accompanying drawings in which Figure 1 is a top plan view of my improved mechanism. Fig. 2 is a central vertical section throughthe same on line 00 n: of Fig. 1. Figs. 3, 4, 5 and 6 are perspective views of different styles of work adapted to be niortised on my improved mecha nism. Fig. 7 is a detail view partly in section of the tool spindle supporting, adjust ing and guiding mechanism. Fig. 8 is a detail longitudinal sectional view of one of the tool spindles. Fig. 9 is a detail perspective view of one of the work holders. Fig. 10 is a perspective view of part of one of the work holders detached. Fig. 11 is a sectional detail on line '12 *v of Fig. 1, illustrating one of the work holders and its actuating mechanism supporting a piece of work. Fig. 12 is a similar view of the work holder, and showing the parts differently ad justcd. Fig. 13 is a detail perspective view of one end of the rock shaft for actuating the work holdcrs. Fig. 14 is a perspective view of one corner of the movable work table and its actuating mechanism. Fig. 15 is an end view of the machine, illustrating a modification in which one operator -an control both sides of the machine. Fig. 16 is an enlarged end view of one of the crank wheels and adjustable eccentrics. Fig. 17 is a side elevation of the same.

In the accompanying drawings which represent one form of my improved mechanism, the supporting frame comprises upright end sections A united together by side or cross frame sections a, which are bolted to the sections A. Supported in vertical guides in the frame sections A is a horizontal guide bar B, which is adjustable by means of feed screws Z) to varying heights relative to the frame, and adapted to be clamped to its adjusted positions by bolts I). The guide bar 13 has ways 6 upon opposite sides, which enable it to support a plurality of carriages C C prefe'ably alternately mounted on the opposite ways, so that the ends of adjacent carriages are enabled to pass each other. The carriages C C are provided with vertical ways 0, which support vertically adjustable members D, which are adjustable vertically by screw rods (Z operated by the hand wheel (5.

Members D attheir upper ends are bifur cated and provided with journal boxes (l in which are journalcd spindles E, the projecting ends of which are split and counterbored to receive the rotary mortising tools 6, said tools being locked in position by nuts (Z fitted by tapered threads to the ends of the spindles, so as to clamp the split ends of the spindles upon the mortising tools. In order to take up and adjust the end play of said spindles, the central portion of each spindle is threaded and has threaded thereon a series of nuts or collars c c c 0", one or more of which are turned on their exterior so as to serve as belt pulleys to drive said spindles, and may also be adjusted in pairs to and from each other by means of a spanner wrench to adjust the spindles encl- 'wise in their hearings, or to take up end play and secure a snug fit between the ends to the tools, and at the same time adj oining tools are permitted to approach each other very closely to produce mortises at short distances apart. By arming both ends of the spindles with mortising tools, two operators are enabled to work from opposite sides at the same machine, or right and left hand pieces of work can be produced on opposite sides of the machine also one operator can control both sides if desired. The several spindles are rotated by means of one or more belts from a countershaft above the machine.

F represents a shaft ournaled' in hearings on the frame A and driven by belt pulley f, which shaft by means of beveled gears f f at opposite ends of the machine serves to drive the shafts f f at opposite ends of the machine, said shafts f 7' being supported by brackets 7" from frame A. Shafts f f each carry a crank wheel and preferably each an. eccentric f, which eccentrics are adjustable to secure varying degrees of eccentricity, and which provide for the reciprocation of four spindle carriages along the ways of bar B, and for varying and adjusting the movement of each spindle carriage independently as required by the work. As shown in Fig. 1, only three spindles are illustrated, but four may be employed if desired without change other than adding and connecting another carriage, while my invention comprises the employment of a greater number of spindles should the work require a greater number of mortises. As illustrated in Fig. 1, the carriage toward the upper end of the sheet is adapted to be driven by means of connecting rod f" attached to eccentric strap engaging the eccentric 7, and if desired another spindle carriage may be reciprocated in like manner from the eccentric f at the opposite end. The opposite carriages are adapted to be driven from the crank'wheels f" by means of connecting rods 7' f the'throw of wnich can. be regulated by shifting the crank pins f to and from the center in the T-slots f Means is also provided at f to vary the length of the'several connecting rods em ployed to drive the spindle carriages. Thus the several spindles may be adjusted to position along their ways and caused to reciprocate along said ways to varying degrees, and are vertically adjustable both together byscrews 5, and independently by screws d, which enables the spindles to be adjusted to the center of narrow or Wide work, or to be adjusted to travel in different horizontal planes, which enables work of the character indicated in Figs. l, and 6 to be accomplished.

illustrated in Fig. 7, one section Z) of the way 6 is pivoted at b, and is angular-1y adjustablerelative to the remaining ways by means of set screws b N seated in ears carrier by the bar l3, and engaging a tongue at the end of section 7), which enables one of said spindle carriages to be adjusted to travel at varying angles relative to the travel of the remaining spindles, and thereby enables the machine to accomplish work of the character indicated in Fig. 3, in which the mortiseg vary angularly. If desired other sections of the carriage ways may be adjustable in the same manner as section b. a

The side frames (1. are provided at opposite ends with horizontal ways h and stops 7t. Mounted upon the ways 71. are work tables H H on opposite sides of the spindles. These tables and parts operating and carried thereby are duplicates of each other. The tables H H as illustrated in Figs. 1 and 2, are independently shifted to and from the mortising tools by means of shafts l operated by hand levers I", said shafts being journaled in the frame pieces a. and provided with crank arms e' carrying roller vi, which engage in recesses 71 formed in opposite ends of the table, so that the rollerserves to shift the tables when the shafts I are rotated. Stops it limit the movement of the tables in one direction and adjustable stops 7t limit the movement of said tables and the depth of cut of the mortising tools in the opposite direction.

J represents the work which may be of circular or rectangular cross section, and pieces designed to be duplicates of each other, frequently vary considerably due to warping and other causes, hence the work holders are required to grasp the work at several points, to straighten or br'ingthe several successive pieces to a uniform position and steady it during the mortising opferation. The work holders comprise the niembersK, which are adjustable on the table sidewise in T-slots in tables H H, and clamped to their adjusted position by nuts 71. liaiembers K carry reversible and vertically adjustable fingers is, which engage the work on the under side and the side farther from the mortising tools, and are reversible to suit work of circular and rectangular cross section. The members K are longitudinally grooved on the under side and serve as guides for the reciprocating bars'K. which carry at their forward ends slotted cross bars 71: vhich are vertically adjustable to accommodate work of varying vertical diameter. Mounted upon the upper end of the cross bars are yielding fingers 76 which are reversible so as to bring either top or bottom Cir face in contact with the work, the beveled face being better adapted to engage work of circular cross section, while the other face is adapted to engage work of rectangular cross section. The fingers k are fulcrumed on the cross bars k at 7c, and their opposite ends held yieldingly in contact with the work by .means of stud bolts and springs 76, the tension of which may be regulated by turning the nuts at the upper end of said studs. The fingers it being vertically adjustable relative to member K and the bars AF and fingers 7c" vertically adjustable relative to member K, enable said parts to be independentl or collectively adjusted to center the work relative to the mortising tools, and to supplement the range of adjustability of the mortising tools.

The several bars K of each table are adapted to be shifted in unison to bring the cross bars 70 into contact with the face of the work next to the mortising too-ls, and the fingers Z in contact with the upper face of the work, as indicated in Figs. 11 and 12, by means of members T1, which are clamped to the rear end of the bars K and are provided with eyes which closely fit a shaft M, which shaft has eccentric studs m at its opposite ends, which studs are attached by links N to brackets n secured to the table. A hand lever P rigidly attached to the shaft M serves to partially rotate the shaft within the eyes of members L, which by reason of the studs m, and links n, cause the bars K to be reeiprocated to or from the mortising tools across the table, and thus to grasp or release the work, thus enabling the work to be rapidly inserted and released, and firmly held during the mortising operation.

As illustrated in Figs. 1 and 2. the respective tables H H and parts carried thereby are adapted to be independently operated either by one or by two operators. In the modification Fig. 15, the rock shafts 2 which serve to reciprocate the tables, are operated by means of a treadle 3 and connecting link l: attached to a crank arm on one of said rock shafts. The rock shafts 2 are actuated in unison by means of a link connecting the crank arms 6 and T of said respective rock shafts together.

The hand lever 8 is connected by link 9 to one end of a lever 1.0, centrally pivoted to the frame A, and the rock shaft M of the opposite table is connected by a crank arm 12 and link 11 to the opposite end of lever 10. Thus when the tables ll H are moved to and from each other the lever 10 moves pivotally without altering the position of rock shafts M M, relative to the respective tables H H, and when the hand lever R is moved. it serves to shift the levers M M on the respective tables in unison to clamp or release the work, and hence in the form Fig. 15 one operator is enabled to control the movements of both tables and their operative parts.

As illustrated in Figs. 16 and 17, the T- slots f are each provided with a scale 20 to facilitate the adjustment of the crank pins fl" to and from the center. The eccentric plates f" are held to the crank wheels 7' by means of screws 21. passing through slots in said eccentric plates, and the hubs of the crank wheels pass through slots 22 in the eccentric plates. Ribs 23 on the eccentric plates engage corresponding recesses in the rear face of the crank wheels to guide the eccentric while being adjusted.

l: have illustrated the respective spindle carriage guides as carried upon a common member I}. which is considered as preferable, but not necessarily essential. The verti cal arrangement of the spindle carriages permits a number of such carriages to be more conveniently reeiprocatcd without interference with each other on the part of the rcci 'n'ocating mechanism.
